Tutorial to Use Infrared Receiver Remote Control With Arduino

Description

Kit theory test distance of about 4 - 9 meters, but the practical application depends on the ambient factors you use, as well as the middle barrier (such as diaphragm, glass, obstructions or other material blocking), receiving head with HX1838 with power work instructions lights, receive 38K frequency any remote coding data.

Specification

Sensor uses HX1838, high sensitivity
Operating voltage 5V
Output form: Digital output.
VCC: 3.3V-5V external voltage
GND: external GND.
IN: external microcontroller I/O port, I/O port has been designed 10K pull-up resistor.

Step 1: Material Preparation

To do this tutorial, you will need :

1. Arduino Uno Board and USB Cable
2. IR Remote Control
3. IR Receiver
4. Jumper Wires
5. LCD 16X2
6. Resistor 10K

Step 2: Pinout Details

Pin 1 is signal
Pin 2 positive power
Pin 3 is ground

Step 3: Pin Connection

1. Connect your IR Receiver to Arduino Uno Board as following :

GND to GND
VCC to 5V
SIGNAL to Arduino's D11 (you could use any digital pin number)

2. Connect your LCD to Arduino Uno Board as following :

VSS to +5VVDD to
GNDRS to 12
RW to GND
E to 11
D4 to 5
D5 to 4
D6 to 3
D7 to 2
A/VSS to +5V
K/VDD to GND

3. Connect 10K Potentiometer to LCD as following :

GND to GND
Data to V0
VCC to +5V

4. After completely connect the whole circuit, connect your Arduino Uno Boad to your computer using USB Cable.

Step 4: IRremote Library

You have to download both of these libraries. Open and extract this to your Arduino's Libraries folder. refer the picture above if you need help on how to extract the libraries.

Step 5: Sample Source Code

decoder.rar is a sample source code that will help you recognizing your ir signal number and remotecontrol.rar is a sample source code that will show you how ir remotes control work. Download both of the sample source code below and this sample source code will be explain on the next step.

Step 6: Recognizing IR Signal

Unpack decoder.rar and open it on your Arduino IDE. Go to Tools > Board > Arduino/Genuino Uno and Tools > Port > select your Arduino's port. Then, upload decoder sample source code on your Arduino board. via USB cable. Wait till Arduino IDE done uploading and open the serial. Now, press any button on your IR Remote control. Your serial monitor should have print you some numbers.

------------------------------------------------------------------------

I click OK button and serial monitor print :

16712445

when I click OK button and hold it for a while. Serial monitor print

16712445
4294967295
4294967295
4294967295

Now, i click number 1 button and hold it for a while. Serial monitor will print

16738455
4294967295
4294967295
4294967295

You can see that when you hold up any button for a few second, you will get a repeating value (4294967295). Thus, it obviously the first number that matter. Now, repeat the same step for all button and record the first number printed when you press you remote control's button. You will need the signal number of your IR remote control it for the next step.

Step 7: Signal Number

This is my IR Remote Control signal number :

OK Button = 16712445
UP Button = 16736925
DOWN Button = 16754775
LEFT Button = 16720605
RIGHT Button = 16761405
Number 0 = 16730805
Number 1 = 16738455
Number 2 = 16750695
Number 3 = 16756815
Number 4 = 16724175
Number 5 = 16718055
Number 6 = 16743045
Number 7 = 16716015
Number 8 = 16726215
Number 9 = 16734885
* Button = 16728765
# Button = 16732845

Step 8: Testing the Remote Control

Now, unpack your remotecontrol.rar and open the .ino file. Notice this code below in the remotecontrol.ino

case 0: //change zero to your IR remote UP button number
lcd.clear();   
lcd.print("UP");
break;

You have to change 0 to whatever number your IR remote button makes. Below is the example code :

case 16736925: 
lcd.clear();
lcd.print("UP"); 
break;

You have to change 0 to your remote control's OK's signal number for case that print lcd.print("OK"). Do this for all button you have on your remote control. Refer the picture above for more understanding. When you have completely updating your case number, check your board and port again, and upload the code into your Arduino Uno Board.
